Product Description

Product DescriptionValves and SeatsValves and Seats are a critical component of the mud pump hydraulic end, engineered to withstand high-frequency operation and severe impact loads. Forged as a single piece from premium 20CrMnTi alloy steel, it undergoes advanced heat treatment with a carburization depth exceeding 1.8 mm, achieving a working surface hardness of HRC60 or higher for exceptional strength and toughness. Its PU, NBR, or HNBR sealing elements deliver outstanding wear resistance, en]suring over 300 hours of effective service and long-term reliable performance in harsh drilling conditions.

Features:1) Material of body and seat: 20CrMnTi/20CrMoCi
2) Valve insert material: NBR, CPU, TPU
3) Structure: full open style, three web style, four web style
4) Depth of Carburized Layer: 1.80~2.22mm
5) Hardness: HRC60-65
6) Temperature tolerance property: -60ºC~100ºC
7) high strength, high toughness, high precision sizes.Classification

Mud Pump Valves and SeatsThe valve and seat are made of forged alloy steel with deep carburized wear surface. We offer a full range of valves and seats which include full open valve and seat, 3 web / 4 web design valve and seat.Full Open Valves and Seats
The valve comes with full open seat features four guide wings. They are either inertia welded to the valve body or uniformly forged with valve body. The urethane insert can be easily snapped on.

3 Web / 4 Web design Valves and SeatsThe 3 web / 4 web seat comes with stem guided valve. The urethane insert is tightened by steel plate and nut. It can be easily replaced with minimum down time. They offer long lasting service life under harsh service conditions.

We could offer Valves and Seats for the following mud pump models, or manufacturing as your drawing:
